Democratic Rep. Keith Ellison attacked Fox News host Sean Hannity on-air tonight in what is surely one of the most explosive and contentious interviews between an anchor and a politician in recent history.

Rep. Ellison began the interview by calling Hannity "the worst excuse for a journalist I've ever seen." He went on to accuse Hannity of violating "every journalistic ethic I have ever heard of" and called him "a shill for the Republican Party."

Hannity calmly endured the attacks from the Minnesota congressman and tried in vain to assure him that he was not a registered Republican, but rather a registered conservative. He finally gave up and told Rep. Ellison to "keep ranting."

The congressman's remarks came after Hannity aired footage of President Obama giving two similar interviews about the looming effects of sequestration, set against a soundtrack of "O Fortuna," from the Carmina Burana. Hannity said the President was "more concerned with fearmongering than finding a solution to the problem he created."
